| -Define Mass Wasting and understand its role as often the first agent of erosion to act on newly weathered rock -Explain the classification system for types of mass wasting describing 1 example of fast and slow -Discuss controls and triggers of mass wasting -Name and describe landscape features created by mass wasting -Differentiate between continental and alpine glaciers in terms of characteristics -explain how ice flows and transports sediment -Describe how scientists discovered that ice flows -name and describe the formation and appearance of landscape features (both erosional and depositional) that are created by glaciers -understand the causes of glaciation -describe the effect of the last ice age on New England's landscape -Give an accurate definition of a desert and dispel myths about deserts -Understand the role of water as an erosional agent in the deserts and contrast to humid regions -discuss erosional and depositional features typical to desert environments -Describe the conditions necissary for effective wind erosion -Explain how wind erodes and transports, and deposits sediment & the features it creates -Describe the zones of groundwater and its role as a reservoir of fresh water for humans, streams, lakes and plants -Explain how groundwater flows including the concpets of porosity and permeability and the factors that affect them -Describe how groundwater transports mineral material and contrast this to other agents -Name and describe the formation and appearance of landscape features (both erosional and depositional) created by groundwater -Identify the components of a watershed/river system & sources of water for them -Describe stream flow including calculating the discharge rate of a stream given the necissary data -describe how running water transports material and the features of erosion and deposition it creates in the landscape -Identify the parts of a wave, how they are created and how they move -Describe how waves erode, transport and deposit sediment including an understanding of the concepts of beach drift/longshore currents and wave refraction -Name and describe the formation and appearance of landscape features (both erosional and depositional) created by waves -Explain and evaluate different engineering solutions designed to deal with beach erosion |

| Across Topic Learning Goals: To identify and describe common erosion/deposition landscape features and explain how they form using specific scientific language as well as to compare and contrast the agents of erosion themselves and their processess. |
